C11 CHECK FOR CORRECT BCM (BODY CONTROL MODULE)
OPERATION |
-
Disconnect and inspect all BCM connectors.
-
Repair:
-
corrosion (install new connector or terminals – clean module pins)
-
damaged or bent pins – install new terminals/pins
-
pushed-out pins – install new pins as necessary
-
Reconnect the BCM connectors. Make sure they seat and latch correctly.
-
Operate the system and determine if the concern is still present.
Is the concern still present?
Yes |
CHECK OASIS for any applicable service articles: TSB , GSB , SSM or FSA
. If a service article exists for this concern, DISCONTINUE this test
